CEF + QT integration on Linux

[developer]

I'm trying to create Qt application with Cef browser working on Linux (Debian Wheezy)
Versions: Qt 5.5, Cef 1547

Basically, I have QWidget with following browser initialization code:

Code: Select all

CefwindowInfo info;
QWindow* win = new QWindow();
this->layout()->addWidget(QWidget::createWindowContainer(win));
info.SetAsChild((CefWindowHandle)win->winId());
CefBrowserHost::CreateBrowser(info, ...);


This code causes Segmentation fault exception with following callstack

Code: Select all

0> g_type_check_instance_cast
1> CefBrowserHostImpl::PlatformCreateWindow()
2> ??


If I comment out the line with info.SetAsChild(..) , everything works as expected save that Cef is launched in separate window, while I need it to be integrated in my Qt application.

Any ideas what am I doing wrong?

Your CEF version is very old. You should update to a currently supported CEF version as listed at https://bitbucket.org/chromiumembedded/ ... -supported

You can compare to how Qt integration was implemented in an existing project like http://tishion.github.io/QCefView/.
